Hi Jim, Witango is more of a "tag" based language, like Lasso, ColdFusion and Python. But of course we have visual "Action" objects which those other language do not.
So technically Witango is not a scripting language, which means you are limited in the range of special operators you have available. Your line below is typically the way it is done. <@ASSIGN name="foo" value="<@CALC EXPR='@@foo + 1'>"> But for where we may lack some special operators, we almost always have a Metatag that can perform a similar operation. So, another lesser known Metatag can also be used like the following, to get what you need: <@NEXTVAL local$foo> Hope this is what you are looking for. Cheers....
